Huckelhoven, Germany (SPX) Feb 02, 2009 4JET Sales+Service GmbH adds a new machine to its portfolio for the thinfilm photovoltaic industry. The new INLINE systems can be used for laser edge deletion, P4 isoscribes and selective perforation of semitransparent solar panels for building integration. Several of the new systems are currently being delivered to customers in Germany and the US. The INLINE systems can be equipped with several laser technologies and allow full area processing of the entire surface of a solar panel. Applications include edge deletion, selective perforation, P4 isolation scribes as well as marking or drilling of glass. The compact unit is a co-development of 4JET and Maschinenbau GEROLD GmbH. The unit is suitable to process all standard panel sizes including G8 formats with 2600x2200mm dimensions. Glass panels are pre-centered and their position is measured precisely. 4JET�s dynamic ABC (Automatic Beam Control) beam delivery system allows to compensate glass warpage and size tolerances of the panels. Depending on the application the units are equipped with diode pumped solid state or fibre lasers. 4JET supplies customer- and application specific process technology and integrates a turnkey solution. Depending on the required throughput, several modules can be installed sequentially. Other than competing laser systems, the 4JET design allows full area processing of the entire panel surface and allows programming of each individual edge width depending on the glass tolerance.
Laser Edge Deletion The precise and abrasion free edge deletion has impact on the durability and efficiency of solar panels. The high level of automation, the cost efficient design and the abrasion free precise ablation process reduces the cost per panel and enhances the quality when compared to other systems such as sand blasting, grinding wheels or other laser systems. The laser process provides a clean surface that has multi Giga Ohm resistance and does not require further treatment prior to the lamination process.

Peripheral and Optional Modules QUOTE: "The INLINE system allows to approach different laser applications in the thinfilm PV backend with an economic modular solution. Eventhough the laser processes and beam sources employed differ with each application, they all require glass handling, positioning of panel and optics, laser safe housing and peripherals, such as vapour evacuation, power meters, cooling or integration in a conveyor system. We offer our customers a solid machine platform as a basis for a cost efficient total solution including the customized laser process development" says Jorg Jetter, founder and CEO of 4JET.
